baseadapter

问题 I am getting force close errors while I try to scroll down my list View in fragment activity, which has 1 image View and 2 text view.

I am retrieving images from sd card from the path. Here, is my logcat out put with errors. 04-05 18:07:02.868: E/AndroidRuntime(3257): FATAL EXCEPTION: main 04-05 18:07:02.868: E

问题 I am trying to create a BaseAdapter which each element has a NumberPicker and a Button. The button's action parameters depends on the value picked in NumberPicker. One solution I thought was creating a setOnClickListener (of the button) inside the onValueChange of the NumberPicker, the problem is onValueChange never gets fired when I change the number. I leave you the code to make it clearer: public class Adapter extends BaseAdapter{ ... public View getView(int position, View convertView,

问题 There was some progress made to the earlier problem. Now there is a new problem. The text in the GridView shows the correct result. However, the images are the same as at the start of the list. For example: If I search for " Sidd " it displays three results but the photos still start as for the users starting with " A ". Attached is a screenshot for clarity. This is the BaseAdapter code: public class TagFriendsAdapter extends BaseAdapter implements Filterable { List<String> arrayListNames;

问题 I'm creating a ListView using CardsUI and I'm planning to create a search using getFilter() . The cards each have a title accessible via getTitle() . Every example of getFilter I've seen has been for just Strings. Does anybody know of any good examples (or can provide a good example) of how I'd adapt getFilter() to match against the titles returned by getTitle() and return the list of objects with a title matching the given string? Thanks. 回答1: I've Implemented this kind of feature in my

问题 I am working on an Android project in which I am retrieving a list of Person's and trying to display them. The Person class contains the profilePhoto as String and I am able to see it saved in DB, after retrieving a List of Person, I am able to print it in Log.d.

问题 In the getView() of a BaseAdapter I load an image into a ImageView using a URL and Picasso. Unfortunately only one image is being loaded. Here is the getView() code : @Override public View getView(int i, View view, ViewGroup viewGroup) { if (view == null) { LayoutInflater inflater = (LayoutInflater) mFragment.getActivity().getSystemService(Context .LAYOUT_INFLATER_SERVICE); view = inflater.inflate(R.layout.layout_card, viewGroup, false); } Log.d("ParseUrl", mCardList.get(i)

问题 The app I'm struggling to make has a simple list and a button present in the bottom no matter what. My problem is that my custom BaseAdapter doesn't show elements. I know that since my elements are only a string I could use an ArrayAdapter, but the assignment requires it. The code: class ListaOrase extends BaseAdapter{ private Activity context; ArrayList<String> orase; public ListaOrase(Activity context){ this.context=context; orase=new ArrayList<String>(); } public void add(String string){
